What’s New

Version 1.15.0

RPN support is here! It’s still in beta - but if you want to make the switch, you’ll find the option to turn it on under the Display menu.
When inserting or deleting open brackets, closing brackets will automatically be added or deleted if it makes sense to do so.

Added modulo operator. Touch and hold on the division symbol to access it.

Added variance, mode, and range to statistics mode.

Added more units in the unit converter.

Improved precision for roots, cube roots, and logs with bases.

Improved UI responsiveness for live results.

An Excellent Useable Solution for Many

First and foremost, I’d like to thank you for developing the best iOS calculator for scientists and engineers. It is simply a joy to use on the iPad, and the features are invaluable. I’m a professor of Physical Chemistry, and the “constants” feature is a huge time saver. I love that recent constants are shown on top for easier access. Also, having the ability to build equations with fillable numbers makes this a great pedagogical tool and a quick way to solve problems using the same equation. I will be encouraging my students to consider this app seriously, and after my class demo today I’m sure they’ll be impressed. I have two suggestions. Saved equations and other settings (e.g. list of common constants) do not carry over to other iOS devices. This syncing is important especially if you’ve created a large number of equations. Secondly, it would be great if there’s an easy way to solve for parameter in an equation. For example, hc/L = 2E-4, where h = Planck’s constant, c = speed of light. Solving for L (wavelength). This is a simple example and I tried using solver mode but doesn’t work. Problems like this don’t need initial guesses. Maple on a PC and Mac does this flawlessly, but their iOS calculator lacks most of the features in TechniCalc. Again, thank you for providing a real useable solution to many people!

Thanks for the five star review - it really helps out! I’ll look into why the solver doesn’t work for that equation. iCloud storage is a good idea. I’ll see what I can do!

This app is crazy good

This app has everything I need. Design and dark mode is beautiful, and the amount of effort in this app is visible. It has matrix operations, fractions and equation solver. With unit conversions! I no longer fear the problems in English units! I got here from a random Reddit suggestion and your app is just the thing I needed. How is this not in top charts! Get this app, it’s not even comparable to many I’ve had to browse through today!

PS: There happens to be some inconsistencies in signs when you’re working with decimal numbers. The magnitude is correct but the sign is always positive. If you have a forum for bug reports, I can report this bug there, but a great app nevertheless

Thank you so much for this! It means a lot to hear people enjoy the app 😊

Edit: You can email me at technicalc_support@icloud.com. Examples of stuff that's broken would really help so I can fix them in the next release!

Quality Calculator App

A vast improvement over the baseline apple calculator, especially on iPad. The interface is understandable and pleasant, and I can imput complex multi-operation calculations without worrying if I messed up order of operations, like on the apple standard calc.

My only two complaints are 1) The unit converter is time consuming to change units, especially when it's often the same few conversions. It would be nice to have a 'Favorites' menu to save conversions. 2) It'd be useful to have a widget of the app so I can access it without constantly opening the app.

Regardless of the two things, this is still the best calculator app I have used.

Developer Response ,

Thanks for the review! It really helps out. For quick access, head on over to settings and enable ‘always available’. Then use ctrl + option + / to open the app. I’ll take a look at speeding unit conversion up. If you have any more ideas, you can always email me through the link in the app!
